Abstract: A novel earth model instrument includes the contents of an existing globe, especially is an instrument for comprehensively revealing the internal structure and laws of motion law of the Earth. The motion state of each part of the Earth is implemented by means of dynamic LED lamps. The globe has eight layers, i.e., layers A, B, C, D, E, F, G and H, of graticule structures (1) from outside to inside; layer A is composed of six large plates and boundary movement directions, and covered with a transparent material having various marks; layers B, C and D are composed of an asthenosphere, a Benioff zone, hot spots and an Asian cold mantle plume (3), and Africa and Oceania hot mantle plumes (4, 7); layer G performs a circumferential displacement motion from east to west relative to the Earth's surface.
